RANGE-BOILER STAND.

Specification of Letters Patent.

Patented July 15,1913.

Application filed March 17, 1913. Serial No. 754,829.

To all whom it may concern Be it known that I, CHARLns L. HOLDEN, acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented a new and useful Range-BoilerStand, of which the following is a specification, reference being had tothe accompanying drawings and to the letters and figures of referencemarked thereon.

This invention relates to the type of stand that is adjustable toupright range boilers of different diameters, the invention havingreference more particularly to stands that are adapted to support rangeboilers of nominal dimensions that may vary slightly in diameter,boilers from different factories designated in the trade to indicatecertain diameters being usually found to be slightly at variance, eithergreater or less than the indicated diameter.

An object of the invention is to provide an improved range boiler standwhich shall be composed of relatively few parts and suitable forconvenient handling and shipment.

A further object is to provide improved means of strong construction foradj ustably connecting the principal parts of the stand together sothat. the parts may be shipped in knocked down condition and be quicklyconnected together, and without requiring the workman to useextraordinary precautions against losing or misplacing detached partsthereof.

A still further object of the invention is to provide an adjustablestand of the above mentioned character that shall be so constructed asto permit a drain pipe from the range boiler to extend down directlythrough the stand in vertical arrangement.

The invention comprises a plurality of leg and arm members provided withvariably adjustable connecting means permitting slight limitedreadjustment after the members are connected together, the inventionconsisting further in the novel features of construction and in theparts and combinations and arrangements of parts as hereinafterparticularly described and also defined in the appended claims.

Referring to the drawings, Figure 1 is a side elevation of the improvedstand and a range boiler thereon partially broken away; Fig. 2, is ahorizontal section of the stand approximately on the plane of the line AA in 1; Fig. 3 is a fragmentary vertical section approximately on theline B B in Fig. 2; Fig. A is a fragmentary elevation showing the innerside of one of the leg and arm members; Fig. 5 is an elevation of theinner side of one of the parts of the means which connect the memberstogether; Fig. 6 is a fragmentary vertical section of the boiler; Fig. 7is a fragmentary section approximately on the line C C in Fig. 3; andFig. 8 is a fragmentary detail of the connecting means.

Like reference characters in the different figures of the drawingsindicate like elements or features of construction herein referred to. I

In the drawings the numeral 1 indicates the body or shell portion ofawell known type of range boiler, 2 the bottom and 3 the top or head ofthe boiler, 4 the cold water supply pipe, 5 the cold Water circulatingpipe, 6 the hot water circulating pipe and 7 the outlet or service pipethrough which the hot water is conducted from the boiler. The lowerportion of the boiler may be advantageously provided with a cleaningplug 8 arranged at the lowest portion to permit the removal of sediment.The bottom 2 being dished is provided at its middle portion with a drainpipe 9 to which a stop-cock 10 is connected, the pipe 9 being of suchlength as may be desired, and a blow off pipe 11 is connected with thestop-cock and may extend vertically down through the floor of a buildingand to a sewer or elsewhere, so that sedimentary matter may beconveniently drawn off from the boiler. The boilers are customarily madein three different nominal sizes but the diameters of the differentsizes are not accurately determined by the different makers so that, forinstance, a boiler supposed to be fifteen inches in diameter may beeither slightly greater or less than that dimension and therefore wouldnot neatly fit upon the stand designed to receive a boiler of thatdiameter.

In carrying out the objects of the invention, an improved leg and armmember is provided, each stand requiring three of the members whichconstitute three leg portions 12, 12 and 12 and three arm portions 18,13 and 13 formed integrally with the leg portions respectively. Thethree members are provided respectively with lateral extensions 14, 14and 1 1 and also other eX- tensions 15, 15 and 15 extending below andsubstantially parallel to the first described extensions. The saidmembers nor mally stand upright and the extensions project horizontallytoward a common The upper one of each of said extensions has twotapering locking keys 16 and 17 on opposite sides thereof, and the lowerone of each of said extensions has two similar keys 18 and 19 011opposite sides thereof, the keys on the lower extension being inalinement with the keys on the upper extension, the smaller end of eachkey being uppermost. The top of each arm portion is provided with anupward projecting lip 20 on the outer edge thereof to guide the boiler,and it is desirable that the lips shall be brought closely into contactwith the exterior of the lower end of the boiler shell.

A novel connector comprises three identically form-ed parts, each beingcast from one and the same pattern and when assembled in the requiredorder constitute three cylindrical segments 21, 21 and 21 havingapproximately tangential arms 22 and 28, 22 and 23, and 22 and 23",respectively, the two arms of a part having two bolt holes 24: and 24therein respectively that receive clamp bolts 25 and 25', each boltrigidly securing two arms of two of the parts respectively to the twoextensions of a leg and arm member. This arrangement provides an openingcentrally of the legs through which the drain pipe 11 extends. The innerside of the two arms 22-and 23 of each connector part have verticalkeyways therein, the arm 22 having three keyways 26, 27 and 28 formed sothat there are two ribs 29 and 30, the opposite arm having also threekeyways 26, 27 and 28 and also ribs 29 and 30". Each keyway is uniformin depth and width throughout and of sufficient diameter to receive thethicker lower portion of either key on the lower one of the leg and armmember extensions and permitting slight lateral movement of the key onthe upper one of the extensions, so thatwhen the clamp bolts arepartially tightened the upper ends of the arm portions may be slightlymoved inward or outward without danger of collapsing of the stand, thekeys on the lower extensions preventing material movement of the legportions of the members. When the bolts are tightened the connectorparts are rigidly secured to the extensions.

The connector parts are loosely connected together for shipment andhandling, by means of the bolts 25, 25, the leg and arm members beingseparate, so that there are no small parts that would be liable to become lost or misplaced during the assembling operations, and with thebolts slackened the extensions of the members are readily insertedbetween the arms of the companion connector parts, the bolts beingreceived between the two extensions of the members. The members areadjusted each with respect to the others to suit the nominal size of therange boiler, after which the bolts are tightened somewhat so as tofirmly connect the members together to support the boiler. After placingthe boiler uprightly upon the upright stand each one or either one ofthe members may be slightly readjusted if required so as to bring thelips 20 close to the boiler, after which the bolts are tightened. Itwill be seen that when slightly readjusting the members to conform tothe boiler, the members can not be accidentally moved outward to anextent that would permit the boiler to fall, and it is evident that theslight amount of adjustment required is not sufficient to destroy thesymmetry of the stand and may be safely made by either unskilled orcareless workmen. It is obvious, however, that the stand may beaccurately adjusted to the boiler if desired or convenient beforesetting them up in position. It will be evident also that the drain pipemay be readily connected to the boiler or disconnected therefrom withoutdisturbing the stand or the boiler.

By reference to Fig. 7 it will be clear that when the members areadjustably connected together the lower ends of the leg portions can nothe accidentally spread apart, the key 18 being firmly held in the keyway28.

Having thus described the invention, what is claimed as new is- 1. Arange boiler stand comprising a plurality of leg and arm members, eachmemher having two lateral extensions thereon extending parallel eachwith the other, the two extensions having two tapering locking keys inalinement on one side thereof, and a connector comprising a plurality ofarms secured to opposite sides of the two extensions of a member, onearm having a plurality of keyways therein that are each uniform in widthand depth throughout, one of the keyways receiving the key and holdingthe larger end of the key of one of the extensions and permittinglateral movement of the key of the companion one of the extensions.

2. In a range boiler stand, the combination with a plurality ofsupporting members having extensions thereon provided on opposite sidesthereof with locking keys, of a plurality of connector parts comprisingeach a curved portion and two arms extending approximately tangentiallyfrom the curved portion and to opposite sides of the extensions andsecured thereto, the inner sides of the arms having each a plurality ofkeyways therein to receive the keys.

3. In a range boiler stand, the combination of a plurality of uprightleg and arm members, each having two lateral extensions thereon providedeach with two locking keys on opposite sides thereof, one extensionbeing below the other, the keys of the lower one of the extensionsbeingbroader than those of the upper one, a. plurality of connectorparts comprising arms embracing opposite sides of said extensions andhaving each a bolt hole therein, each arm having; a keyway that isuniform in width through- 10 out and receiving said keys, a keyway ofeach arm holding said broader key and permitting; lateralmovementtherein of the key of the upper one of said extensions, andbolts secured in said holes and securing said extensions to said arms,the bolts extending between the two extensions of the respectivemembers.

In testimony whereof, I affix my signature in presence of two Witnesses.
